' Original application filed February 5, 1924, Serial No. 690,861. Divided and this 3, 1925. Serial No. 12,895. 1

This application is a division of my original application S. N. 690,861, filed February 5 1924.

This invention relates to means for the 5 centrifugal treatment of various fluids without resort to rotating parts. It is adapted for employment in cleaning and purifying many liquids, gases and vapors but as a leading use is in the urification of water it will herein be exemphfied in a form and arrangement suitable to such use.

The invention will be readily understood on reference to the drawings that form part of this specification; in which, Fig. 1 1s a vertical section of an apparatus embodying this invention. Fig. 2 1s a cross section on the line 2-2 of Fig. 1; Fig. 3 is a crosssection on the line 3-3 of Fig. 1, and Fig. 4 illustrates the use of fying a liquid.

These drawings show the invention in the form of a centrifugal unit that is adapted to filter or purify an upward moving stream. By way of example, as illustrated in Fig. 4

the stream is taken from the basin 244 at the point 245 and is set in motion by-a centrifugal pump 246; the purified fluid being delivered to the reservoir 257, while the rejected impurities are returned to the basin.

3o That use will conveniently serve to exemplify many others.

Passing-through the pump 246 the water is discharged into the intake elbow 247 of the centrifugal unit, here under discussion. This elbow is the means of connection with the casing 248 of the unit, which casing contains the centrifugal bowl 251 and the cen- I trifugal tuyere ring 250. The latter. comprises a circumferential series of inwardly 4o directed opera'tively overlapping tangential tuyeres and is dependedupon to set the fluid into rapid rotation within the ring 250 and bowl 251. Those parts may be supported from the part 248 by making the bowl integral therewith, as suggested by Fig. 2. Passing through the centrifugal elements, the

' clarified liquid is discharged through the top opening 252, centrally positioned withln the the apparatus in puri- CENTRIFUGAL APPARATUS.

application filed March annular abutment portion 253. The bowl has a central conical part 254 from which an outlet pipe 255 extends downward, passing through a stufiing box 256' at the bottom of the part 247.

As illustrated, only the clarified water from the outlet pipe 252 is discharged into the reservoir 257. The foul liquids or waters from the centrifugal outlet 251 of the bowl and from the central outlet, are in this case returned to the source 244, as shown in Fig. 4. But under other conditions the differing products or filter savings from the pipes 255 and 251 will be saved. In some cases just such use of the apparatus will be made its chief use, it being obvious that a true classification of the heavier substances is accomplished in the peripheral and central outlets here provided. Furthermore, these pipes may contain one or more' valves for controlling their outputs. v The dow ngoing stream through. the central outlet may also be varied as to quality by varying the spread of the cone'254; and again, the downflow at the center of the bowl serves effectually to destroy any vortex at the bottom of the centrlfugal elements, which, if permitted. might conceivably cause the return of very fine impurities to the upgoing main stream discharging through the top, outlet 252. The illustrated apparatus is therefore both a clarifier and a classifier of the finest possibilities. 1

Having thus described my invention I claim as new and desire to secure by Letters Patent I 1. YA suitable upper easing having an outlet in its top in combination with a multiply tuyered tangential tuyere ring of greater diameter than said outlet, concentric therewith and attached to said top and presenting its upper end to said top, a stationary centrif-' ugal bowl closingthe lower end of'said ring, a tangential peripheral discharge leading from said bowl outward through said casing, a sink at the center of said bowl and a duct ing through said casing.

2. A suitable upper casing having an outlet in its top in combination with a multiply tuyred tangential tuyere ring of greater d1- ameter than said outlet, concentric there- 5 with and presenting its upper end to said top, a stationary centrifugal bowl closing the lower end of said ring, a tangential. peripherai discharge leading from said. bowl outward through said casing, and a duct leading downwardfrom said bowl' passing through said casing.

In testimony whereof, I have hereunto set my hand this 26th day of February, 1925.
